First report on the herpetofauna of Palaio Trikeri island (Pagasetic gulf, Greece)

Palaio Trikeri is a small 2.5 km² island in the Pagasetic gulf. We conducted the first herpetological survey on the island and confirmed the presence of 5 reptile species, specifically 4 species of lizards and 1 species of snake. Brief observations on other fauna were also made and are mentioned in the discussion. The identity of green lizards on Palaio Trikeri needs to be investigated, while further fieldwork could be carried out in the future in order to uncover the potential presence of additional species.
